iatented. Dec. 12, 1905.

Application filedJune 14,1905. Serial no. 265,152..

To all whont it Wtay concern:

Be it known that I, DANIEL J. CLARK, a citizen of the United States, anda resident of J ersey City, in the county of Hudson and State of NewJersey, have invented certain new and useful Improvements inIncandescent Man tles of which the following is a specification.

1 My invention relates to incandescent mant es.

It has for its object to provide an incandescent mantle comprising aplurality of hollow sections placed together to form a ring, whereby theilluminating-surface of a single mantle is increased, and if one of thesections becomes burned out or broken it may be removed and replaced bya new section, thus effecting a great saving of the mantles.

It has for a further object to provide a mantle of the character setforth embodying advantages in point ofsimplicity and inexpensiveness ofconstruction, attractiveness, and effectiveness in use.

In the drawings, Figure 1 is a sectional view showing my mantlesupported on a burner. Fig. 2 is a perspective view of the mantle. Fig.3 is a perspective view of a modified form of the mantle.

In all the figures of the drawings illustrating my invention likereference characters designate corresponding parts.

Referring to Figs. 1. and 2 of the drawings, 1 designates a burner-headconnectedwith the gassupply by a pipe 2 and comprising'a castingembodying a central chamber 3, a reticulated cap 4 therein, anddownwardly-extending radiating burners 5, leading from the chamber3. amantle-hanger and mantle, to behereinafter described, in the properrelation to the burners, bosses 6 are formed on the burners, and each isprovided with a vertical bore 7, intersected by horizontalscrew-threaded bore 8, engaged by a set-screw 9. A globe 10, open at thetop and closed at the bottom, is supported on the supply-pipe, so as tosurround the burner, mantle, and hanger.

The hanger employed for supporting the mantle comprises independentframes and -ment each flame of the burner will be To provide means forsupporting 26, each formed of a single piece of wire bent to present ahorizontal portion 27, having large openings connected by narrowpassages and a vertically-extending portion 28, adapted to be insertedinto one of the bores 7 in the burner and be secured therein by thesetscrew 9.

The incandescent mantle, which is supported on the hanger abovedescribed, comprises independent hollow curved sections and 31,substantially U-shaped in cross-section and having pockets 32, 33, and34, into which the burners project, connected by narrow passages and 36.By this arrangeartially confined within a pocket of the maIItle.Referring now to the modification shown by Fig. 3 of the drawings, thisform of mantle comprises a lurality of hollow independent substantia lysemicircular sections and 41. The hanger for supporting this form ofmantle comprises independent substantially semicircular frames 42 and43, having vertically-extending portions 43.

These hangers are not herein claimed, as.

they form the subject of an application which I have filed concurrentlyherewith.

I do not wish to be understood as limiting myself to the precise detailsand arrangements of parts shown and described, but reserve the right toall modifications within the scope of my invention. 1

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. An incandescent mantle consisting of a plurality of independenthollow sections inclosing a space therebetween, substantially asdescribed.

2. An incandescent mantle consisting of a plurality of independenthollow sections inclosing as ace therebetween, each section having a purality' of pockets, substantially as described.

3. A ring-like incandescent mantle, comrising a plurality of independentcurved iiollow sections substantially U -shaped in cross-section,substantially as described.

4. A ring-like incandescent mantle, comp'rising a plurality ofindependent curved municating pockets, substantially as de- 10 scribed.
